Latest release: v0.8.0
Disambiguation4/5
Most tools have clearly distinct purposes, such as 'add_element' vs 'add_relationship' vs 'add_node_to_view'. However, there is some overlap between 'export_model_content' and 'export_model_to_file', and between 'validate_model' and 'validate_semantics', though descriptions help differentiate them.
Naming Consistency3/5
Tool names use a mix of verbs like 'add', 'create', 'update', 'delete', 'export', 'load', 'query', 'validate', etc. Without a consistent verb_noun pattern, but the names are still descriptive and readable.
Tool Count3/5
At 45 tools, the count is high but justifiable given the complexity of ArchiMate modeling, covering CRUD for multiple entity types, validation, layout, and reporting. However, some redundancy exists with batch operations and similar query tools.
Completeness4/5
The tool set covers core model lifecycle: creation, editing, deletion, validation, export, and layout. Notable gaps include lack of update/delete for notes and limited folder management, but overall domain coverage is strong.
Average 4.5/5 across 45 of 45 tools scored. Lowest: 2.1/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate destructiveHint=true, and the description's verb 'Apply' implies modification without adding detail. The description does not disclose whether operations are reversible, require prior validation, or affect other model aspects, failing to enrich beyond the annotated destructive nature.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single brief sentence, but it sacrifices necessary detail. While concise, it is not front-loaded with key information (e.g., tool scope, effect), and the jargon reduces efficiency. Every sentence should earn its place; this one does not fully serve the agent.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (6 parameters, destructiveHint, output schema), the description is incomplete. It does not explain return values, parameter roles, or prerequisites. The output schema exists but is not referenced, leaving gaps in agent understanding.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% with six parameters, but the description mentions none. Parameters like 'repair_ids', 'auto_layout', and 'rollback_on_error' are undefined, forcing the agent to rely solely on parameter names which may be ambiguous.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states 'Apply selected deterministic semantic relationship repairs,' which identifies a specific action and resource. However, the term 'deterministic semantic relationship repairs' is jargon and not explained, reducing clarity compared to more self-explanatory sibling tools like 'validate_semantics'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description offers no guidance on when to use this tool versus alternatives. With many sibling tools for editing, validation, and reporting, the lack of explicit when-to-use/when-not-to-use advice leaves the agent to infer usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so the agent knows it's a safe read operation. The description adds no further behavioral details—such as whether the tool checks against a metamodel or what happens with missing parameters. Since annotations cover safety, this is adequate but not insightful.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
A single sentence with no fluff, placing the core action first. However, the extreme brevity sacrifices necessary detail; a sentence or two more would improve clarity without harming conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With 6 parameters, an output schema, and many sibling tools, the description is too sparse. It fails to explain parameter choices (e.g., id vs type, strict_archimate), leaving the agent under-informed for correct selection and invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must explain parameters. It only hints that 'source/target ids or types' are used, ignoring 'intent', 'strict_archimate', and the interplay between id and type parameters. This is insufficient for correct invocation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool recommends valid relationship types for source/target IDs or types, using a specific verb and resource. It distinguishes from most siblings like 'add_relationship' or 'get_relationship_compatibility', though the latter is closely related and not explicitly differentiated.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like 'get_relationship_compatibility' or 'add_relationship'. The description does not explain the intended context, prerequisites, or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint=true, so the description adds minimal behavioral context. It does not disclose what 'valid' means or potential edge cases.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single concise sentence with no filler, though it could be slightly more informative without losing brevity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of ArchiMate relationships, the description lacks explanation of what constitutes valid options (e.g., metamodel rules) and does not leverage the presence of an output schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, and the description adds no meaning to the source_type and target_type parameters beyond their names.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool returns valid ArchiMate relationship options for given source and target types, distinguishing it from siblings like recommend_relationship.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies when to use (to get valid relationship options) but does not provide explicit guidance on alternatives or when not to use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint=true. The description adds value by detailing the CSV format (base columns and custom properties as 'Property:' columns) and the error case 'ModelNotFoundError'. However, it does not disclose potential performance implications or any limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is short and well-structured. It starts with the primary purpose, then details the output columns, and ends with return format and error. Every sentence is informative with no waste.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no parameters and an output schema, the description covers the CSV content, return envelope, and a relevant error. It could mention if the export is limited by model size or if there are any side effects, but overall it is sufficiently complete for a simple read operation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are no parameters, so schema coverage is trivially 100%. The description does not need to add parameter information, meeting the baseline expectation for no-parameter tools.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Export all active model elements as a CSV string', specifying the verb and resource. It distinguishes from siblings like 'export_model_content' and 'export_relationships_to_csv' by focusing on elements, but does not explicitly differentiate.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description mentions an error case but provides no guidance on when to use this tool versus alternatives like 'export_model_content' or 'export_relationships_to_csv'. No when-not-to-use or prerequisites are stated.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate destructiveHint=true and readOnlyHint=false. The description adds context by detailing that the view and its visual components are removed while underlying elements/relationships are preserved, which exceeds the annotation information.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and well-structured with labeled sections (Args, Returns, Errors). Every sentence adds value, and there is no unnecessary fluff. Could potentially be slightly shorter, but current length is justified.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the main behavioral aspects: deletion scope, return value, and error condition. Given the presence of an output schema (implied by 'Success envelope'), the description is complete enough for an agent to understand the tool's effect.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% description coverage, so the description must compensate. The Args section describes view_id as 'ID of the view to delete', which adds basic meaning but no additional constraints or format details. This is adequate for a single string parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Delete an ArchiMate view from the active model' and specifies what is removed (view and visual nodes/connections) and what is NOT removed (underlying elements and relationships). This distinguishes it from sibling tools like delete_element and delete_relationship.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for deleting views but does not explicitly state when to use this tool versus alternatives or provide exclusion criteria. The context is clear from the tool name and sibling list, but no direct guidance is given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate idempotentHint=true, readOnlyHint=false, and destructiveHint=false. The description adds important behavioral details: parent directories are created, the layout engine is per-call only, and specific error conditions like suggestions for invalid strategies. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with Args, Returns, and Errors sections. It front-loads the core action. While detailed, it remains readable and avoids redundancy, though some parameter details could be trimmed.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description has a Returns section (output schema exists) and an Errors section, providing good coverage of outcomes. However, 5 undocumented parameters reduce completeness for a tool of this complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 10 parameters with 0% description coverage. The description explains 5 parameters (path, output_format, auto_layout, layout_strategy, layout_engine) and their defaults/conditions. However, 5 parameters (quality_gate, allow_orphans, allow_visual_issues, allow_semantic_issues, include_quality_report) are not mentioned, leaving gaps.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description starts with 'Serialize the active model and write it to a local file,' which is a specific verb+resource pair. It also clarifies the preferred use case for producing a .archimate file that Archi can open directly, distinguishing it from sibling tools like load_model_from_file or export_model_content.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description states it is 'Preferred when the user wants a .archimate file Archi can open directly,' giving clear context. However, it does not explicitly mention when not to use it or list alternative tools for other scenarios.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses numerous behavioral traits beyond the annotations: advisory nature, scoring algorithm (seven checks, score range, status thresholds), guarantee that 'limited' is the floor, and the error condition (ModelNotFoundError). This adds significant value given the tool has readOnlyHint and openWorldHint annotations that only hint at safety and completeness.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with clear sections (advisory, scoring, returns, errors) and front-loads the core purpose. It is slightly verbose—especially the return list—but every sentence serves a purpose. A minor trim would improve conciseness without losing clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 2 optional parameters and an output schema (implied), the description covers behavior, scoring interpretation, and error conditions comprehensively. However, the lack of input parameter explanations leaves a gap, preventing a perfect score. The output schema is mentioned, so return value details aren't strictly needed, but the description still documents them thoroughly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description should explain the two parameters (include_hard_validation, include_quality_assurance_views), but it does not. It focuses solely on the output structure. While the schema provides names and defaults, the description adds no meaning about what these boolean flags control or their effects.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool returns 'advisory TOGAF-oriented readiness findings' and distinguishes it from validation tools by emphasizing its advisory nature. The verb 'assess' combined with 'readiness findings' makes the purpose specific and distinct from sibling tools like validate_model or build_quality_report.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly says 'Advisory only' and explains that the compliance_claim is always false, indicating it should be used for review, not formal conformance. It provides scoring context but does not directly mention when to avoid using it or list alternative tools for conformance checking, which would strengthen guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate readOnlyHint=true, and the description adds behavioral details: it returns a success envelope with two dicts (elements_by_type and relationships_by_type) and can raise ModelNotFoundError. This goes beyond the annotations, though it does not cover potential rate limits or authorization needs.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise (two short paragraphs) and front-loaded with the main purpose. Every sentence adds value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has no parameters and an output schema exists, the description sufficiently covers the return structure and error condition. It is complete for the tool's simplicity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With zero parameters and 100% schema coverage, the description is not expected to add parameter information. The baseline for 0 params is 4, and the description does not need to compensate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool counts active model content grouped by ArchiMate type, specifying both elements and relationships. This distinguishes it from sibling tools like query_elements and query_relationships, which return lists rather than aggregated counts.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not provide explicit guidance on when to use this tool versus alternatives. While the purpose implies it is for summary statistics, it lacks any 'when to use' or 'when not to use' statements, and no alternative tools are mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already set destructiveHint=true, but the description adds that pyArchimate removes visual connections, which is helpful. It also documents the error case. It does not mention other behavioral details like irreversibility or permission requirements, but overall adds value beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and well-structured: main action, side effect, parameters, returns, errors. Every sentence is relevant and earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given low complexity (1 parameter, output schema present), the description covers input, side effect, output, and error. Minor gap: does not clarify what 'active model' means, but context likely known. Overall adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description includes an Args section explaining the parameter as 'ID of the relationship to delete,' which adds meaning beyond the schema's type-only definition. Could be more detailed about the format or source of IDs.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it deletes an ArchiMate relationship from the active model, specifying the resource and action. It also mentions the side effect of removing visual connections, distinguishing it from update or other delete operations.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not explicitly state when to use this tool versus alternatives like update_relationship or delete_element. Usage is implied but not guided with exclusions or comparison to siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate mutation (readOnlyHint=false) and non-destructiveness (destructiveHint=false). The description adds value by explaining the rollback_on_error behavior, the success envelope with node_ids and count, and specific error types (ModelOperationError, ElementNotFoundError). This goes beyond what annotations provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with a clear main sentence, a bullet-like explanation of node shape, and separate sections for args, returns, and errors. It is relatively concise but could be tightened slightly; the node item shape example adds clarity without being overly verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (3 parameters, nested objects, output schema exists), the description covers purpose, parameters, returns, and errors. It implies the view must exist and handles failure modes. The output schema is mentioned, so return values are explained. It does not explicitly list prerequisites but is largely complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage, so the description carries the full burden. It explains all three parameters: view_id (target view ID), nodes (list of node objects with shape details including optional/required fields), and rollback_on_error (default true). This adds significant meaning beyond the bare schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Add multiple visual nodes to a view in one call,' specifying the resource (view) and the action (add nodes). It distinguishes from the sibling tool 'add_node_to_view' by being a batch variant and explains that each node supports the same fields. This provides clear purpose and differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies that this tool is for adding multiple nodes in one call, contrasting with the single-node sibling. It mentions the rollback_on_error behavior and error handling, which provides context. However, it lacks explicit guidance on when to use this tool versus alternatives or when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, readOnlyHint=false, openWorldHint=false. The description adds value by detailing that pyArchimate removes dependent concepts, providing behavioral context beyond the structured fields.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with clear sections (Args, Returns, Errors). The first sentence immediately states the purpose, and every sentence adds value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple one-parameter tool with annotations and an output schema present, the description fully covers the operation: deletion, cascade effects, and error conditions. It is complete and sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description provides minimal extra meaning: 'element_id: ID of the element to delete.' This is adequate but does not elaborate on format or other constraints, earning a baseline score of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it deletes an ArchiMate element from the active model, using a specific verb and resource. It distinguishes itself from sibling tools like delete_relationship and delete_view by focusing on elements.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explains it removes dependent concepts (relationships, visual nodes), indicating it is the comprehensive delete for elements. It does not explicitly state when to use alternatives like delete_relationship, but the context implies appropriate usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint=true, so safety is clear. The description adds value by detailing the return structure (three arrays and count fields) and the ModelNotFoundError, which are beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with three sentences: purpose, usage hint, and returns/errors. Front-loaded with the main action, no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With zero parameters and an output schema present, the description sufficiently explains the return fields and error possibilities. It is complete for a simple list tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are zero parameters, so baseline 4 applies per rules (no parameters to describe). The description does not need to add parameter info as the schema is empty and fully covered.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description specifies 'List elements with no relationships and/or no view placement,' clearly stating the verb and resource. It distinguishes from sibling tools like query_elements by focusing on orphan detection.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description says 'Useful for finding gaps before completing a model,' which implies usage context but does not explicitly compare to sibling tools or state when not to use. No exclusions or alternatives are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so safety is clear. The description adds valuable behavioral context: return fields (including relationships not yet drawn) and specific error conditions (ModelNotFoundError, ViewNotFoundError). No contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with a clear structure: a one-line summary followed by Args, Returns, Errors sections. Every sentence adds value, no fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has only one parameter, is read-only, and has an output schema, the description fully covers what the agent needs: what it does, what it returns, and possible errors. No gaps remain.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description compensates by documenting the single parameter 'view_id: ID of the view to summarize.' This adds meaning beyond the schema's type definition.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('Summarize') and resource ('a single view'), and lists exactly what it returns: node count, connection count, gaps. This clearly distinguishes it from sibling tools that modify or create views.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
No parameters exist, so the description cannot add parameter semantics. Baseline is 4 for zero-parameter tools. The description compensates by detailing return fields, which adds value beyond schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool validates visual references in the active model, specifying it checks invalid connections and nodes. It distinguishes itself from the sibling 'validate_semantics' by clarifying one is for visual references and the other for semantic checks.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says when to use (for visual references) and when not to (use validate_semantics for semantic checks). Also clarifies that diagram-only annotation connectors are excluded from defect reporting, giving clear guidance on what is and isn't checked.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses extensive behavioral traits beyond annotations: notes are visual only, have no ArchiMate element, do not appear in queries, x/y are kept exactly across layout, layout does not move nodes under a note, and notes are not updatable or deletable yet. Annotations (readOnlyHint=false, destructiveHint=false) are consistent with description.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured with clear sections: intro, usage guidance, Args, Returns, Errors, and limitations. Each sentence adds value, no redundancy. Front-loaded with key purpose and distinction.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Completely covers purpose, usage, all parameters, return values (with output schema noted), error types, and limitations. For a tool with 8 parameters and complexity, the description is thorough and actionable.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 0% description coverage, but the description fully explains each parameter: text (non-empty, verbatim, escape sequences not interpreted), x/y (exact integers), width/height (defaults), connect_to_node_ids (accepted ID types), note_id (uniqueness across entire model, namespacing advice). Adds significant value beyond schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool adds a diagram-only note (sticky annotation) to a view. It distinguishes from grouping elements and other tools by specifying that notes are visual only, have no ArchiMate element, and do not participate in model tree or validation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says when to use (to comment on a diagram) and when not to use (do not create a Grouping element for comments). Provides reasoning that notes do not pollute the model tree or participate in validation, guiding the agent to choose the right tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide destructiveHint but the description goes further: it details the replacement behavior, return envelope structure (`data.model_id`, `data.model_info`), error conditions (`INVALID_MODEL_NAME`), and parameter effects. No contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured: purpose paragraph, then Args/Returns/Errors sections. Front-loaded with the core action. Every sentence adds unique value; no redundant or vague statements.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (3 params, destructive, output schema not provided), the description covers all necessary aspects: parameters, return shape, errors, usage context, and relation to sibling tools. No missing information.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so description must carry full burden. It comprehensively describes all 3 parameters: name (non-empty string), description (optional, comes back as documentation), properties (optional, keys/values coerced to strings). No gaps.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states what the tool does: 'Create a new empty ArchiMate model and make it the active model.' It distinguishes from sibling tools by explicitly referencing `load_model_*` tools and `update_model`, creating a clear usage boundary.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
It explicitly states when to call: 'before any element/relationship/view tool', and provides alternatives for different tasks. It also notes that `update_model` should be used for later metadata changes.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the readOnlyHint annotation, the description details what the tool includes (model info, summaries, type counts, etc.) and mentions error conditions (ModelNotFoundError). No contradictions with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with separate paragraphs for purpose, usage, args, returns, and errors. It is concise yet comprehensive, with no redundant information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema and the detailed description covering purpose, parameters, return, and errors, the description is fully complete. It does not rely on the output schema to explain return values.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Despite 0% schema description coverage, the description fully documents all three parameters with defaults, meanings, and constraints (e.g., sample_limit clamped to 0-50). This compensates completely.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool inspects the active model without dumping full XML or source code, and lists the types of data it combines. It distinguishes itself from related tools by specifying it is an inspection-only step after loading and before editing.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states 'Use this immediately after loading an existing model and before editing.' This provides clear guidance on when to use the tool and implicitly indicates it is not for editing.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare destructiveHint=true, and description reinforces 'replaces active model'. Additionally, it details file path behavior, format expectations, error types, and response structure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured with main description, Args, Returns, Errors sections. Front-loaded with purpose, every sentence adds value, no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given complexity (loading, optional inspection, multiple formats, errors) and presence of output schema, description covers all aspects: inputs, outputs, errors, and distinguishes from 40+ sibling tools.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 5 parameters with 0% description coverage, but description fully explains each: path (tilde expansion, relative resolution), content_format (enumeration of formats), inspect_after_load (default true, compact summary), include_semantic_validation (default true), sample_limit (clamped 0-50).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description uses specific verb 'Load' with resource 'ArchiMate model from a local file' and explicitly states it replaces the active model. It distinguishes from sibling 'load_model_from_content' for raw XML, making purpose unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states preferred entry point for local .archimate or XML files, advises alternative for raw text, and explains that default inspection avoids extra round trips.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds significant behavior beyond annotations: 'rendering never moves anything', 'SVG is a rendering, NOT a third model format', and 'The markup is written to disk and never returned.' It also explains token size to justify not returning the SVG, and clarifys file creation behavior (expanding ~, creating parent dirs). No contradictions with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with a clear summary first, then usage details, parameter explanations, return value list, and error cases. Every sentence adds value, and there is no redundancy or wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (file system handling, return data, error conditions, sibling differentiation), the description is fully complete. It covers all necessary context: when to use, what the output is, how parameters work, what returns and errors occur, and how it differs from related tools.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, but the description fully compensates: 'view_id: ID of the view to render.' and 'path: Output path on the MCP server's filesystem (.svg conventionally). `~` is expanded, relative paths resolve against the server's CWD, and parent directories are created if missing.' This adds crucial meaning beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Render one view to an SVG file so a human can look at the diagram,' providing a specific verb and resource. It also distinguishes from siblings like export_model_to_file and auto_layout_view by clarifying that SVG is not a model format and cannot be imported back.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicit guidance on when to use (to check layout, drop into document/chat) and when not to use (not a substitute for export_model_to_file). It also recommends using auto_layout_view first if layout needs work, providing a clear alternative.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
